I haven't used my 50mm F/1.2 L for a while, but for this recent shoot I was very glad I had it with me. I was shooting for this client on city streets at dusk and had her sit at a sidewalk cafe. The light was pretty much gone by that time, just enough to focus. Wish the 5D3 would illuminate the focus point!!
ISO: 1600, F/1.2, 1/160th
When she turned her head a little more, I could not keep both eyes in acceptable focus. Fortunately, I took lots of shots at this location! Doing close portraits at F/1.2 does not give you a high keeper rate, that's for sure.
The blurred shapes behind the subject are a group of people sitting at a table just behind her. As someone once said, F/1.2 doesn't blur the background, it obliterates it. So true! And so convenient sometimes.
